the art to which it appertains to make and use the same.

This invention relates to improvements in stackers and particularly to stackers having an endless conveyer or elevating mechanism.

One object of the invention is to provide a stacker of this character having an improved construction and arrangement of conveyer or elevator supporting and oper ating mechanism whereby the conveyer may be operated at any angle or inclination and which will permit the stacker to be turned and operated in any direction.

Another object is to provide a conveyer formed in sections and having improved means for holding the sections in adjusted positions.

A further object is to provide a stacker of this character which will be simple, strong, and durable in construction, efficient and reliable in.operation and in which the elevating mechanisinmay be extended to any desired length.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a side view of my improved stacker showing the elevating mechanism in a raised position in full lines and in a lowered position in dotted lines; Fig. 2 is a similar view taken at right angles to Fig. 1; Fig. 3 is a vertical longitudinal section of the stacker taken on the line 33 of Fig. 2; Fig. 1- is a horizontal sectional view of the base of the machine; Fig. 5 is a side view of the base and elevator supporting mechanism of the conveyer and a cross sectional view of the elevator or conveyer taken on the line 55 of Fig. 1; Fig. 6 is an enlarged side view of the upper portion of the main section of the conveyer and a portion of the adjacent end of the adjustable section of the conveyer showing more clearly the manner in which the adjustable section is held in its adjusted positions, parts being broken away and in section. Fig. 7 is a view similar to Fig. 1 illustrating the application of a threshed grain conveyer which is designed to take the place of the unthreshed grain conveyer shown in the previous figures of the drawings. Fig. 8 is a detailed longitudinal section of the threshed grain conveyer shown in Fig. 7.

My improved stacker comprises a stationary base or platform 1 having suitable supporting feet 2 which are adapted to rest on the ground or other surface on which the stacker is arranged. Formed on or rigidly secured to the base 1 is an upwardly projecting centrally disposed cylindrical post or standard 3 having in its upper surface an annular ball race in which is arranged an annular series of bearing balls 4;. Revolubly mounted on and telescopically engaged with the post or standard 3 is an elevator or conveyer supporting member which is in the form of a hollow cylinder 5 closed at its upper end said closed upper end resting on the bearing balls d as shown. This telescopic engagement of the post and cylinder provides a strong, reliable engagement of these parts while permitting them to be revoluble relative to each other. On the closed upper end of the cylinder are formed a pair of oppositely disposed upwardly projecting bearing lugs 6 on the upper ends of which are formed bearings 7.

Engaged with the bearings 7 is an elevator or conveyer supporting shaft 8 on which is pivotally mounted an unthreshed grain conveyer or elevator trough 9, said trough having secured to its opposite sides and near the lower ends thereof bearing plates 10 having therein apertures to receive the shaft 8 by means of which the elevator trough 9 is pivotally connected to the shaft. In the lower end of the trough 9 is revolubly mounted a conveyer supporting and operating shaft 11 having thereon sprocket gears 12 with which are engaged the chains 13 of an endless conveyer 14, the body portion of which is formed by a series of slats 15 which are spaced apart and connected at their ends to the chains 12. The conveyer 14 is engaged at the upper end of the trough with sprocket gears '16 fixed on an upper conveyer supporting shaft 17 mounted in the upper end of the trough as shown.

Revolubly mounted in the base 1 at one side thereof is a main drive shaft 18 having fixed thereon a drive pulley 19 with which is engaged a belt 20 whereby the shaft may be driven by a suitable power. Fixed on one end of the shaft 18 is a sprocket gear 21 which is connected by a sprocket chain 22 to a sprocket gear 23 fixed On the adjacent end of a counter shaft 24 which is mounted in suitable bearings beneath the center of the base 1 as shown. Also fixed on the shaft 24 near one end thereof is a spur gear pinion 25 which projects upwardly through a slot in the base '1. Loosely mounted on the shaft 24 near the opposite end thereof is a spur gear 26 which also projects upwardly through a slot in the base 1. Mounted in suitable bearings on the lower side of the center of the base 1 and at right angles to the plane of the shaft 24 is a shaft 27. Loosely mounted on the shaft 27 and spaced the same distance from the center of the base the gears 25 and 26 are idle gears 28 the purpose of which will be hereinafter doscribod. Arranged around the lower portion of the conveyor supporting cylinder 5 and engaged with gears 2526 and 28 is a double face gear ring 29. The gear ring 29 when thus arranged is driven by the gear 25 which is fixed on the counter shaft 24 and said ring runs idly or loosely on the gears 26 and 28 and is thereby supported or held in a horizontal position.

Fixed on one side of the cylinder 5 near the lower end thereof is a stud shaft 30' on which is rovolubly mounted a spur gear 31 having fixed .thoreto or formed integral therewith a sprocket gear 32. The gear 31 has an operative engagement with the teeth on the upper'side of the gear ring 30 whereby said gear and the sprocket gear 32 are driven by said gear ring. The gear 32 is connected by a sprocket chain 33 With a sprocket gear 34 which is mounted on the adjacent end of the elevator supporting shaft 8. Formed on or rigidly secured to the gear 34 is a smaller sprocket gear 35 which is connected by a chain 36 to a sprocket gear 37 on the adjacent end of the lower conveyor supporting and operating shaft 11.

By thus constructing and arranging the elevator operating mechanism it will be seen that the gear ring 29 will be continuously driven by the gear 23 on the counter shaft 24, said gear 23 engaging the teeth on the lower side of the gear ring. The movement of the ring when thus driven will be imparted through the gears 31 and 32 and the sprocket chain 33 to the sprocket gears 34 and 35 the movement'of which is transmitted by the chain 36 to the gear 37 and shaft 11 of the conveyor thereby driving the latter in the proper direction for carrying the material thrown thereon upwardly and discharging the material from the upper end of the stacker. 7

As hereinbefore stated the conveyor j desired angle or inclination. The trough is supported in its adjusted positions by a prop comprising two bars 38 the ends of which are overlapped and held in sliding engagement by clips 39 one of which is arranged on; each of the inner ends of the bars and has a sliding engagement with'the adjacent bar as shown. The outer endof the lower bar 38 is pivotally secured to a bracket 40 on one side of the upper end of the cylinder 5 while the outer end of the upper bar 38 is pivotally secured in any suitable manner to the lower slde of the conveyor trough as shown. The clips 39 are pivoted to the ends of the bars 38 and when the weight of the conveyor or elevator is applied to the bars the clip of one bar will be drawn into frictional engagement with the adjacent portion of the opposite bar and will tightly bind the bars 38 together intight frictional engagement and thus support'the elevator or conveyor at the angle or inclination to which the same has been adjusted.

The elevator may be provided with extensions of which there may be any desired number each of said extensions comprising a trough 41 in the ends of which are revolubly mounted conveyor supporting and operating shafts 42 on which are fixed conveyor supporting gears 43 with which the conveyor chains 44 are engaged. The shaft 42 in the lower end of the conveyor trough chain 46 with the sprocket gear-47 on the adjacent extended end of the upper conveyor shaft 17 whereby the. movement of this shaft is imparted to the shaft 42 of the lower edges, segmental extensions 49 onthe.

lower edges of which are a series of ratchet teeth 50. The projecting ends of the hinge plates 48 engage the outer sides of the adjacent ends of the sides of the trough 41 and are pivotally mounted on the extended ends of the main conveyor shaft 42 of the extension conveyor trough 41 whereby the latter is hingedly connected to the upper end of the main conveyor trough 9.

Secured to the outer sides of the conveyor trough 41 adjacent to the ends of the hinge plates 48, are guide plates 51 having on their lower ends downwardly projecting segmental guide arms 52 with which tho-adjacent pawls 54 are held in operative engagement with the teeth 50 by coiled springs 55 which are arranged in the channels 58 and bear against the outer ends of the pawls 54 as is clearly shown in Fig. 6 of the drawings. The pawls 54 when thus engaged with the teeth 50 firmly support the extension trough 41 in the position to which the same has been adjusted. v

In order to release the pawls 54 to permit the extension conveyer trough 41 to be adjusted, I preferably provide pawl releasing dis as 56 which are pivotally secured to the opposite sides of the trough 41 and to which are eccentrically connected one end of links 57 the opposite ends of which are loosely connected with the outer ends of the pawls 54 whereby when said disks 56 are turned in the proper direction the pawls will be disengaged from the teeth 50 of the segmental extensions 49 of the hinge plates 48, thus permitting the conveyer trough 41 to be swung upwardly or downwardly to the desired position.

In Fig. 7 of the drawings, the stacker is shown as provided with a threshed grain conveyer which is designed to take the place of the unthreshed conveyer trough 9 and which comprises a hollow rectangular body 58 the lower end of which is closed by a segmental end plate 59 which is hinged at one end to the lower end of the outer side of the body 58 and which has its inner end bent to form a right angular off set edge which engages the lower end of the inner side of the body 58 and is held in engagement therewith and in closed position by a turn button 61 pivoted on the inner side of the body as shown. In the outer side of the trough 58 near the lower end thereof is formed an inlet opening 62 over which is arranged a hopper 63 into which threshed grain is placed. The upper end of the body 58 is also closed and has connected to the lower or inner side a discharge spout 64 into which the grain is discharged from the buckets of an endless conveyer hereinafter described. From the spout 64 the grain is discharged into a wagon or other receptacle.

The threshed grain conveyer is pivotally secured to the bearing lugs 6 of the conveyer supporting cylinder 5 by bearing plates 65 which correspond to the bearing plates 10 of the unthreshed grain conveyer, said plates 65 having a pivotal engagement with the conveyer supporting shaft 8 on which is fixedly mounted sprocket gears 34 and 85.

Revolubly mounted near the lower end of the body 58 of the threshed grain conveyer,

is a lower conveyer supporting shaft 66 on which is fixed a sprocket gear 67. Revolubly mounted in the upper end of the body 58 is an upper conveyer supporting and operating shaft 68 on which 1s fixed a sprocket gear 69. Engaged with the sprocket gears Gland 69 is an endless conveyer chain '70 on which at suitable intervals are secured grain elevating buckets 71 which are preferably ii-shaped as shown. Arranged longitudinally through the center of the body 58 is a conveyer supporting partition 72 over the upperv or outer side of whichthe outer or working stretch of the conveyer chain is designed to travel and which supports the buckets carrying the grain while being elevated. One end of the conveyer supporting and operating shaft 68 is extended beyond one side of the body 58 and has fixed thereon a sprocket gear 73 which is connected by a sprocket chain 74 with the sprocket gear 35 on the main c0nveyelr supporting shaft 8 whereby the movement of said shaft is transmitted to the shaft 68 for operating the conveyer chain 70 carrying the buckets 71.

The. threshed grain conveyer when arranged as herein shown and described, is designed, when in an operative position to stand in a substantially perpendicular position as shown in Fig. 7 of the drawings and the conveyer is held in this position by means of hooks 75 on the outer sides of the conveyer near the lower ends thereof said hooks being adapted to engage staples or other suitable forms of keepers 7 6 arranged on the cylinder 5 of the supporting mechanism as shown. In the operation of the threshed grain conveyer when constructed as herein shown and described, the threshed grain is shoveled or otherwise placed in the hopper 63 and is discharged therefrom into the segmental lower end of the. body 58 of the conveyer from whence the grain is taken up by the buckets 71 and thereby conveyed or elevated to the upper end of the conveyer at which point the grain is discharged from the buckets through the spout 64 into the wagon or receptacle provided to receive the same. By constructing and arranging the threshed grain conveyer as herein shown and described, it will be seen that the same may be readily substituted for the unthreshed grain conveyer shown in the first figures of the drawings and the stacker thus employed for elevating any kind of threshed grain.

By supporting the conveying or elevating mechanism of the stacker as herein shown and described it will be seen that the unthreshed grain conveyer or elevator may be readily adjusted and supported at an inclination for conveying hay, grain, corn, fodder or any other material to the top of astack or into a mow or other place and it will also be seen that by manually swinging the cylinder 5 around on the post or stand: ard 3 that the conveying mechanism for either the unthreshed or threshed grain maybe arranged to elevate the material in any direction desired.

From the foregoing description in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation;

, Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is:

In a stacker, the combination with a base having thereon a bearing post, of an elevator supporting cylinder telescopically engaged with and revolubly mountedon and having a ball bearing engagement with said a post, bearing lugs formed on said cylinder and pro ec-tmg above the same, an elevator trough.
